Improvement in tilting trucks



UNITED STATES PATENT OFFICE.

GEORGE M. SHEPARD, OF BATH, MAINE, ASSIGNOR OF ONE-HALF HIS RIGHT TOWILLIAM HEATH, OF SAME PLAGE.

TILTING TRUCKS.

Specification forming part of Letters Patent No. 150,979., dated May 19,1874; application filed March 4, 1874.

To all whom it may concern:

Be it known that I, GEORGE M. SEEPARD, of Bath, in the county ofSagadahoc, State of Maine, have invented a certain new and usefulImprovement in Tilting Trucks, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which my invention appertains to make and use thesame,reference being had to the accompanying drawing forming a part of thisspecification, in which- Figure 1 is a side elevation of my improvedtruck. Fig. 2 is a plan or bottom view of the same.

Like letters refer to like parts in the different figures of thedrawing.

My invention relates more especially to that class of trucks designedfor trundling or moving heavy casks; and consists in a novelconstruction and arrangement of the parts, as hereinafter more fully setforth and claimed, the object being to provide a simpler and moreeffective device of this character than is now in common use.

The eXtreme simplicity of my invention renders an elaborate descriptionunnecessary.

In Fig. 1, A is the body or frame-work of the truck, and B C the rollersor wheels. A cask or hogsllead is represented by the dotted lines D, theend pieces orcross-beams a b of the frame being concaved to conform tothe cask.

It is well known to all who have occasion to handle heavy filled casksthat it is very difficult to move them from place to place, or to drawfrom them when the liquid becomes low and the cask continues to resthorizontally on y The center of motion, when the truck is loaded, is inthe central axial line of the wheel or roller B,whieh is placed slightlyforward of the center of gravity, the two being nearly coincident, sothat but very little power will be' required to tilt the truck, or tipit forward, and thus enable the cask to be readily drawn from in allstages of fullness. Y

I am aware that in Letters Patent numbered 68,811, granted to F. VanDoren in 1868, a skid and friction-roller are described, having some ofthe characteristics of my invention, although essentially differenttherefrom..

When my improved truckis at rest, a cask mounted on the same will be ina horizontal position, and yet may be easily tipped or tilted to drawfrom; but a cask mounted on the skid described in said patent willassume an inclined position when the skid is at rest, unless additionalmeans are employed to level the same. I therefore do not claim anythingshown or described in the patent of said Van Doren, when in and ofitself considered; but

What I claim is-` A tilting cask-truck consisting of the frame A, havingthe coneaved cross-beams a b, and provided with the rollers B O,combined to operate in the manner and for the purpose set forth.
